large file support in glib

[Sven Neumann <sven gimp org>]

Hi,

we've discovered that for some obscure reasons g_file_test() fails on
files larger than 2GB. I also expect g_io_channel_seek() to fail since
it uses off_t. A clean and simple solution to this problem would be to
add AC_SYS_LARGE_FILE to configure.in.  This macro would also allow to
easily disable large file support using the --disable-largefile
configure option. Unfortunately autoconf-2.13 does not support
AC_SYS_LARGE_FILE. So the patch would boil down to:

Probably it's time to do the switch to autoconf-2.5 now. What do you
think?


Salut, Sven
